Application filed Jma'y 25, 1909. Serial No. 474983 To -oZZ whom alt may co'n cam:

rim and held there by means which will pe'mi t the 'enovel or 'eplueement git an individual block without duslodgng the remaining bloeks com rising the tre, said blocks being a 'range: on the wheel rim in 'aplm-ility of longiLud-inally-extending 'lies eo that the joints in each series of blooks will alternate in position with respeet to the "joints between blooks of adi-&cent series.

The invention further contemplai'es so dnstvuoting the tire that the festening 'neens the'efo' will fixedly hold the resilient hlocks thereof secn'e ly in position when de- 'sted and yet of surah Construction as to permit of the ready 'enm'l of individual blocks lhe'ef'om, the u'i'nngenenl of the bloeks being such :s to ine'ea se the resilienoy of the ti'e and tnction of the same on the 'odwiy and rednce the liahility of slipp'ng i `01' skidding of the tire.

i With the oregoing and other `objeots in viewg the invention consists in the novel {cjonstrncton oonbinaton and errangenent of parts eonstt'tmT r the invention to be here'nz'iter speeficnl y described and illusst'tted in the acconpanying dx'awiigs which jfo'n ai part hereof whe'ein is shown the pre- :ei'red embodiment of the invention, but it isto be understand that changes, Veria- ;tiene ,and modifiefitions can he resorted to which come within the seope of the claims he'pennto appended.

M In'the d'awings :in which similar reference nu norals indicate like 'parte in the different Figure l is a cross sectional View of g rim and tire portion of a wheel oonstructed, in accerdanee with this inventior, also showing' in 'cross section a -tit emogether with the holrlfast means for seem-ing 'the same, seid holdfast means amtaged in operative reltion therew-ith; Fig. 2 is e plan of a portion of a wheel rim and ti re mouwad therein embodyin this invention. Fig. 3 -is a detail of `one o the -holdfeet devices fot' the tire; and, Fig. l is a seotional View -o line X of Fig. 2.

In the (h awi ngs, the :reference numeral l denotes the rim which -is of the -ordiney elencher type provided with in-turned side flen es 2, and while this .type of rim is used to il' ustrate the invention m connection with the tire to be he'einetter described, other forms of rim may be employed by varyi-n the base portion of the tire to be sente( therein.

Mounted on the rim l are -a dpdnreli' of 'ubbebodies, hereinafler enom-mwtod bloeks, arra ed in porallel series, the blocks of one series eing denominated by the re'f erence nuneral 3 and those in the `other series by the reference numersl These blocks are all similar end each of .them :consists of a tread portion 5 from which depemd lateral po'tions 6 to a base portion having one side !provided with a groove `to receive one of the -flenges 2 of the rim and with e portion 7 below said groove to fit under the inturned hook-sheped portion of said rim. The opposite side of each,of the bloeks is provided with e shoulder 8 prezfe'ably inc ined at an appropriate a ngle, for -a ur poso to' be later described. Embedde 'in each of the bloeks is a traisverselyextending wire or 'bar 9. The ende 10 of enoh ei' the blOClS are ,prefembly inolined and Me provided with e t'ansversely-extending shoulder 1 1, for a purpose 'to -be later described. When each series -o f btlooks is positioned on a wheel rim :the ende o-f the bloeks of each series are in abu tting relation with each other whereby theve is &ol-med between them a transve'sly extending notcln by reason of the fact that the -nolined shoulde's 11 of eontiguous hlooks m'e i-n registe'ing i'elation with the portion below Sflld lOb &poet to the points of union or matches of the blocks of' on edjaoent series, as clearly shown -i n Fjg. *2. It wil l be further a *erent that whale only two series of resrent bloe'ks are shown on the rim 1, .tt will :be entirely with-in the scopo of this i nventon to provide n Wider rim and plaee thereon three or more series of resilie't blocks, all arranged as described with reference to each other, us the two series 3 and 4 shown and described in the drawings.

In order to hold the rcsilient blocks 3 and 4 in position, there is placed in the groovc formed by the registering shoulders 8 of the two series oi" bloclrs a plurdlity of meml'ers 12 preferably of sheet metal, V-shnaed in cross section with :in integral later ly-cx tending si'ilarly-sha'ed arn 13, the nclination of the portions of the members 12 and its laternllyextending nrm 13 being such :15 to conform to and seat upon the registering shoulders S between the two series 3 und 4 and also to fit in the rcgistering shoulders 11 formed in the ends of tltljttt`t'llll bloclts in each series. The end of the member 12 is preferzbly chamfered or cnt away :tt ll. us: shown in Fig. and the enl 1:3 of the arni 13 is also sinil'rl provided. The ntm 19 is also provided with a groove or cut uwy portion 16 for a purpose to be later de scribt d.

In setting up a tire of this description, the blocks are arranged n two series, ;s

shown in 'the drtwings, with the joints between adjacent bloeks of onc series filter miting in position with the joints between adjacent bloclcs of the. proxinate series. The members 12 nre then forced into the groove formed between atljacent series until they rest upon the registering shoulders 8 of the members thcreof with 'the arms 13 positioned upon the registering shouldcrs 11 of contiguous blocks ofone series. In positioning the members 12 the end 15 of each arm 13 will be forced under one of the overhanging and inturned fiangcs 2 of the rim so as to lock thereunder. The second member is then placed in osition with the arm 13 thereof turned in t e opposite direction a nd in the alternatin notch so thutthe later-al arm 13 thereof s arranged to he seated on the registering shoulders 11 of the blocks of the other series with its end locked under the opposite fhnge 2 of the rim. I

This method is continued with the arms 13 alternately in opposite directions to sent in the alternating notches between the hlocks of each series. The main portions'of these members 12 will be of such zi length that when the lateral arms 13 are positoned on the re iste'ing shoulders 11 the chnmfered or nc ined ends 14- of the main portion thereof Will lock` under the next preeedig member. hen these members hnve been positioned as just described, a circumferentiall -extendi r wire `17 is then seztcd in the shnped hannel forned b the members 12 `and isghelda ainst disp aeement by the inclned sides of t e member 12 and'also h reason of the fact that it passes through tlie openings or notches 16 of one of the side walls of the lateral arms 13 of each of the members 12. The wire 17 is provided with thrcaded ends to receive a turn-buckle 18 by which the wire is contracted, causing the same to firmly force the members 12 downwardly upon the registening shoulders 8, thereby holding the tirc sccurely in position on the rim.

It will be noted that :s the outer end of the lateral arm 13 of each of the members 12 engages under one of the later-al fianges 2 of the rim the said arms are tlso held in position against tlispl-.cement and as the contraction of the wre 17 forces the mem bers 12 downwarlly, it also forces the laterl arms 13 downwardly into snng engagement with the trnnsversely--x[ending registering shoulders 11, thns holding; the hlocks 3 and 4 sccurely against trnnsverse or longitudinal norc'ent in the wheel rin and also against nnintentionnl dispheemcnt.

In order to prevent any possible movement of the arms 13 the flangcs 2 are preferably inlentcd ut 19 by means of a suitable tool, either npplied to the lhng'es previous to the seting of the Lire or fterward, as preterred, bt these indentations engagethe V==haped ends 15 of the arms 13, preventing :my hngitndinal movement thereof.

In order to repair the tire by the removal of :n injured or worn block, the turn-buckle 18 is nmnipulnted to release the tension on the wire 17 snflieiently to pernit the remoral of one or more of the members 19, after which the injnred or worn block may be taken ont and re )lneed by a\ new one. the members 12 replaced and tension restored to the wirc 17 which etl'ectually seat:: not only the new block but also the entire tire seenrely on the rim.
